7 .To all whom it 772 (13 concern .Be it known that 1, CHARLES Hermes WmLIAMS, a citizen of the United States, residin at city of Chicago,county of Cook, and tate of Illinois, have invented a certain new anduseful improvement in Safety- Hanger Supports for Brake-Beams, of whichthe following is a full, clear and exact description, such as willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, forming partof this specification, in which Figural is a side elevational view ofone form of my invention. Fig. 2 is a sectional view on line 2-2ofFig. 1. Fig. 3 is a sectional view on line 33 of Fig. l. -Fig. 4: is adetail view of the supporting bracket. Fig. 5 is a side elevational viewof a modified form of my invention. Fig. 6 is a sectional view on linefi -6 of Fig. 5. Fig. 7 is a side elevational view of another modifiedform of my invention. Fig. 8 is a sectional view on line 8-8 of Fig. 7.Fig. 9

am also enabled by this arrangement to use angles or T bars, I beams,etc.,,shapes which in themselves are which, after being is a sideclevational view of another modified form of my invention. Fig. 1G is ase'ctional view on line 10--10 of Fig. 9.

Thisinvention relates to safety hanger supports for brake beams, but itis also useful in connection with sliding third and. fourth pointsupports. Supports of this "character have heretofore been made of lightjspring'bars, but to get the proper resiliency and flexibility, the barshave sometimes proven in service to be too light and in consequence theyhave been bent so as to take a permanent set which impairsthen-oiliciency, especially when used as third or fourth point supports;

It is the purpose of my present invention to make the hanger or support,as the case may be, of strong'material which in itself 'is practicallynon-resilient or nonficxible,

- and to employ springs to give to this 'stifi' two springs.

bar or support, the necessary flexibility. 1

strong and unbending and.

flexed, will return to their normal positions.

In the accompanying drawings, 1 haveshown several arrangements ofsprings, such as a single heavy spring at the center, 'or

llhis will allow one side of the I bar to go down while the other goesup, which gives the desirable results corresponding to the action ofshoes and beams on inside hung'brakes where the bar is used as a thirdor fourth point support. The bar may be in one piece, as shown in Figs.1 to 5, or divided at the center, as shown in Fig. 9.

In the drawings, 1 indicates'the spring plank of the truck I 2 is abrake beam having a third point supporting shoe 3 at its inner end.-

. l is an angle bar serving as a track plate for the third pointsupport. v

5 is a bracket casting secured to the underside of the spring plank andformed with a channel or recess therethrough for receiving the bar 4.-and permitting a rocking movement of said bar or angle therein.

6 is a bolt passing through spring plank,

1, bracket 5, and also through an enlarged opening in the bar 4, wherebysaid bar is held against longitudinal displacement, but is permitted torock. Nut 7 is on the lower end of this bolt, which nut may be held inposition by a cotter pin.

8 are springs seated in housings at the ends of the bracket 5, saidsprings bearing against the horizontal flange of the bar 4:

so as to hold the same up against the'.under-' side of the spring plank.V

The construction above described permits (if theends of the bar 4, suchmovement being sufficient. to accommodate the necessary brake beams, nutbolt 6-7 may be removed,

which will enable the withdrawal of barge.

a limited amount of movement vertically The space in the bracket 5 whichwill enable the vertical play of bar 4 therein, is

sufficient to accommodate the angle or bend. of the bar in its insertionand remoyal. Bolt.

6 must, of course, be removed-to permit this longitudinal movement;

In Fig. 5, I have shown another formof my invention in which I dispensewith the bracket 5 above described, and in lieu there-. of employ bolts9 which pass through en larged openings in the horizontal flange of bar4, wherebylongitudinal' displacement of the bar is prevented.These'bolts 9 carry ends on which are arranged springs 11, saidspringsbearing against the underside of the washers or spring'sea tslO-at their lower of this construction is horizontal flange of thebar 1. The operation of this construction is the same as that describedwith respect to Figs. 1 to at.

In Figs. 7 and 8, l have shown another form of my invention in whichthere are two bolts 12 passing through enlarged open ings of thehorizontal flange of the bar 4. These bolts support a tie bar 13 to thecenter of which is secured a leaf spring 1% whose free ends are formedwith enlarged openingsijor are slotted, to receive the bolts 12, and earagainst the underside of the horizontal flange of bar 4. The operationsimilar to those heretofore described.

In Figs. 9 and 10, I have shown a con.- struction in which bar 1 isdivided at its center into two parts l each being I at 15 to brackets 16secured to the plan-kt The ends of these sections 4 have enlargedopenings formed therein to cooperate with bolts 17. 18 are springsinterposed between the inner ends ofthe sections 4; and the tin dersideof the spring plank; In this construction, the sections 4 of the bar areindependently movable.'

hat Iclaim is:

1. In a safety hanger, or third or fourth point support for brake beams,the combi nation with a part of a car truck, of a non-flexible barmounted thereon, and means gor permitting yielding movement of saidpivoted 2. In a safety hanger, or third or fourth point support forbrake beams, the co nation of a part of a car truck, a rigid arrangedthereon, means for preven longitudinal movement of said to pe' mit arocking movement thereof, and yie 'i ing means cooperating with the barfor holding it in normal position.

3. In a safety hanger, or third or foin'th point support for brakebeams, the coinbination of a part of a car truck, a bar mounted thereonand having a pivotal or rocking movement relative thereto, and yieldingmeans cooperating with-the said bar to hold the same in normal position.

4;. In a safety hanger, or third or fourth point support for brakebeams, the coinb m nation o'if'a part of a car truck, a z: .z' mountedthereon and capable of rocli movement relative thereto, means for preventing longitudinal movement of said oar, said means being detachableso as to per 55 init the ren'iovhl of the bar, and yielding 'neanscooperating with said bar to hold the same li1- -Il0fnlt11 position.

In testimony whereof I hereunto attix my signature in the presence oftwo witnesses this 7th day of July, 1916.
